DESCRIPTION OF THE PREFERRED EMBODIMENT

With reference now to the drawings, and in particular to FIG. 1 thereof, a new and improved child stroller and infant carrier system embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described.

The present invention, the new and improved child stroller and infant carrier system, is comprised of a plurality of components. Such components in their broadest context include a stroller, an infant carrier and coupling components therebetween. Such components are individually configured and correlated with respect to each other so as to attain the desired objective.

One of the two major components of the system 10 of the present invention is a stroller 12. The stroller is constructed to have a frame 14. The frame is formed to include two parallel main diagonal supports with each being formed of an upper tube 16 and a parallel lower tube 18. The upper and lower tubes are pivotally coupled together through hinges 20. In addition, releasable locks 22 allow for the bending of the tubes about the pivot point or locking them in a generally fixed orientation with respect to each other parallel but offset. The lower ends 24 of the upper tubes and the upper ends 26 of the lower tubes constitute the location for the pivoting and the locking.

Each lower tube has at its lower extent a wheel 30 rotatable about vertical and horizontal axes. These constitute casters. In addition, a pair of generally vertical tubes 32 are also provided. Each is coupled at its upper end to an intermediate point 34 of the upper tube. Each vertical tube has a rotatable wheel with a releasable brake 36 at its lower end. Also as part of the frame is a pair of generally horizontal tubes 38. Each such horizontal tube has a forward end 40 and a rearward end 42 with an intermediate point 44. Pivotally coupled to the intermediate point of the horizontal tube is an intermediate point 46 of the vertical tube. In addition, there is a forward point 48 of the horizontal tube which is pivotally coupled by a pin 50 to an intermediate point 52 of the lower tube.

Coupled as part of the frame structure are generally parallel upstanding pylons 56. Such pylons are laterally spaced from each other. They are secured to the lower tube adjacent to their upper ends. Resilient locking fingers 58 are movable outwardly from the pylons to ensure retention of a carrier onto the frame.

The last component of the system 10 is an infant carrier 70. Such infant carrier is formed with an upstanding front 72, back 74, and sides 76. Such carrier is fabricated of a rigid material, preferably plastic. the carrier is also formed with a pivotable handle 78. The pivotable handle is in an inverted U-shaped configuration. It extends upwardly from intermediate point 80 on the sides of the carrier.

The carrier is formed with an aperture 82 on each side. Such apertures are positionable to releasably couple by a sliding motion with the pylons of the frame. In this manner, the carrier may be selectively joint and separated from the stroller.

As to the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided.

Further details of the carrier can be found in U.S. Pat. No. 4,943,113, the subject matter of which is incorporated herein by reference.

With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.

Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
